To all whom it may concern.'

Be it known that'I, JOHN W. Mosul/1ER, a citizen of the United States, residing at East Worcester, in the county of Otsego and State of Newl York, have invented vcertain new and useful Improvements inv Shaft- Driven Pivotal Hubs, of which the follow- .aording eXtra strength, suiiicient oil-carrying capacity, ready access to all wearing portions, and easy operation with a minimum of friction when in the hardest service.

'0f the accompanying drawings setting forth the construction and arrangement of the various parts of this invention, Figure 1 represents a vertical section lengthwise of the axle and showing all the `parts assem# bled. Fig. 2 is a- Hat face view` of the slotted driving plate!v Fig. 3is an inside view of one of the s hells of the ball or universal joint. Fig. l 1s a section of the ball of the Ell lill

.astride of the ball universal joint showing the pivoted yoke and the lug in the slot of the ball. Fig. 5 is an end view of the yoke or Spanner of the ball joint, and shows a side view or the lug or block that engages the uving recess or slot in the surface of vthe In the drawings and throughout the description, the same letter is used to refer to the same part.

Considering the drawings, the-axle A is Y- hollow, and it has a4 biturcated or forked end a. lBy means of the pivot pins B and h the axle box C has one end pivotally secured to the axle and may swing in a horizontal plane when the aule is in its customary horizontal positionn 'lhe sleeve or socket c is provided for the attachment ol the steering rod usual in such connections.v

'ln Fig. l it will be noted that the axle box C has an annular shoulder D, and that a sleeve al encircling the aule bor` is con-- strncted to engage the shoulder "lL -llllae Specification of Letters Patent.

Sleeve d may thus be .moved lengthwise to the right on the axle box but ischeld bythe axle box shoulder D from movement in the other direction.' j i Encircling the axle box and the sleeve al is the hub E, and it will be observed that the hub has an internal annular recess c that opens upon -the sleeve d. Urdinarily, the sleeve is somewhat recessed correspondingly, and a chamber of considerable size and extent is thus formed for the reception of suitable lubricant that finds its way to the other parts, especially tothe bearings F and y which are arranged at the ends of the sleeve d'. f I

Within the hollow aXle A is the driven shaft G, having a ball giat its end. The ball g is 'a Inelnber of a universal joint, and is has a transverse, superficial groove l-l, in which movably lits the curved lug or block it, that forms an integral part of the curved yoke or Spanner Il that is pivotally secured to the ballg y the diametrical bolt y'. `llt will be seen that the yoke d' projects beyond are placed together to form a socket for the ball, they also form a curved recess'v or path L occupied and traveled by the projecting portion of the yoke al.

The journal M passes through the aule box C and is revoluble therein. At one end it is enlarged and constructed with a cavity or seat m into which the twin shells K and 7c t. A pin N passing through the shells and through the journal M secures the shells i within the cavity m and upon and about the ball end g of the shaft Gr.' lt is believed to be clear, therefore, .that the revolution oil the shaft turns the journal lll/l similarly.

Side thrust upon the hub is thrown partly upon thel bearing F and is taken up by thefengagement of the sleeve and -the shoulder D. No one of the hearings receives the entire side thrust or jar vinv either \direction. The AWheel hub, bearings andsleeve are easily removed for Yany attentionrby detaching'the dust cap and -aXle nut, and any Worn or broken member.

a revoluble hub mounted upon the aXlebox,

andmeans secured .to the outer end of the yjournal and constructed to transmit the rotation of the journal to the hub and to hold the llub in place upon the axlebox.
